THOMAS A. LATHROP, OF CANTON, OHIO.

HYDROCARBON VAPORIZER AND BURNER.

SPECIFICATION forming part of Letters Patent No. 445,225, dated January 27, 1891.

Application filed September 15, 1890. Serial No. 364,969. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS A. LATHRoP, a citizen of the United States, and a resident of Canton, county of Stark, State ofOhio, have invented a new and useful Improvement in Hydrocarbon Vaporizers and Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in hydrocarbon Vaporizers and burners; and it consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claim.

Figure 1 of the accompanying drawings is a view in perspective, partly sectional, of a hydrocarbon vaporizer and burner illustrating my invention; Fig. 2, a longitudinal section of a fragment of the burner, and Fig. 3 a transverse section on line cc to as, Fig. 1.

Similar letters of reference will indicate corresponding parts in all of the figures of the d rawi n gs.

A represents the tube or casing, having one of its ends closed by a removable head B, and interjacent its ends a flange portion 0, by which the burner is secured to a furnace. Near the outer or closed end portion of the tube or casing A is provided an air-pipe or neck portion D and airregulating valve E, the pipe F leading from the blower or place of supply to the burner.

The oil-pipe portion of the burner is constructed substantially as shown in the drawings. The conical heater and spreader G is preferably made of cast metal, and is provided with a chambered portion a and threaded perforations b and c. The oil-supply pipe H has one of its ends threaded and turned into the threaded aperture Z), the other end connected with pipe leading to the source of supply, while a nozzle J is turned into the threaded aperture 0, as shown in Fig. 2.

The pipe H, with heater and nozzle attached, is placed in the casing A, as shown in Fig. 1, the large end portion of the heater in the end of the tube to impinge the flow of atomized oil and air against the inner wall of the tube.

In operation a blast of air is forced from a conveniently situated blower through the pipe F and past the regulating-valve F. and into the casing A in the direction shown by the arrow. The oil is raised or drawn from the holder and driven by a pump (preferably of the rotary form) through the pipe F to the heating-chamber a, where its temperature is raised to a high degree, and ejected from the nozzle J in a spray to meet the current of air before referred to, by which the jet of heated and sprayed oil is atomized and turned back over the heated surface of the cone, which impinges the atoms of oil and air against the hot wall of the casing, which delivers the air and oil in a vaporous or highly-inflammable state to the furnace, where it is consumed, burning from the end of the casing through the furnace, the length of flame being determined by the'flow of oil and air into the burner or casing A. The end of the tube A and the heater and spreader G, if only flush with the inside wall of the furnace, will become heated to a high degree, sufficiently so to heat the supply of air as well as the oil, by which a perfect combustion of the oil is secured.

The heating of the heater and spreader may be determined by the setting of the burner and the furnace-lining, giving such exposure of the burner to the fire as may be required to give the heater the required temperature.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with an inclosing tube, of an air-duct communicating therewith, an oilsupply pipe projecting into said tube, and a spreader secured to said pipe and provided with a chambered portion which communicates with said oil-pipe, and an outlet to said chambered portion, said outlet directing the oil and vapor in a direction opposite that of its entrance into said hollowed chamber, and forming with said oil-pipe and hollowed chamher a continuous circulating passage, substantially as set forth.

In testimony whereof I have hereunto set my hand this 11th day of September, A. D. 1890.

THOMAS A. LATHROP.
